Windows computers come with several management functions in the form of small programs called applets. We can invoke these applets with our Liberty BASIC code. We can cause things like the control panel, desktop settings, and accessibility options applets to run.

The control panel looks like this:

The desktop properties dialog looks like this:

The following commands show how to use the rundll32.exe program to invoke these applets. Control panel applets have the extension *.cpl. Most of the examples come from the shell32.dll, but there are a few other goodies in the list.

These commands simply call up dialogs. They do not cause any changes to be made to the user's computer. The user can make changes in the dialogs, or cancel them.

The Command List

The following RUN commands are meant to be used individually. Do not attempt to run the entire code below as is. Extract the commands you need and insert them into your code in appropriate places, one at a time. The comments accompanying each RUN command explain the functions.
